Embodiment 1

[0032] The detergent container 2 described in this embodiment is provided with two probes 9 for detecting the presence or absence of detergent. When there is a margin, an open circuit can be formed in advance.

[0033] Such as image 3 As shown, the two probes 9 are inserted from the top of the detergent container from top to bottom, and the lengths of the ends in the detergent container are different to form a drop.

[0034] Alternatively, one probe is located on the upper part of the detergent container and inserted from top to bottom, and the other probe is located on the side of the lower part of the detergent container and inserted from the side to the inside, and the height of the insertion end has a drop.

Embodiment 2

[0036]The washing machine described in the present invention is a washing machine of various types, which can be a drum washing machine, a wave-wheel washing machine or others. Can be provided with a pedestal 11 at the bottom of the washing machine, the detergent container 2 is arranged in the pedestal 11, as figure 2 shown.

Embodiment 3

[0038] Such as Figure 4 As shown, the dispenser box 3 described in this embodiment is provided with a fixed container 31 and a dispenser 32, the lower part of the dispenser box is a washing powder box and a softener box 33, and the bottom of the fixed container 31 is provided with an inlet 311 and an outlet 312 , the top is provided with a ventilation hole, and the fixed container 31 is also provided with two capacity probes for detecting the set volume of detergent. A solenoid valve 34 is arranged between them, and the height of the outlet 312 is higher than the height of the water inlet pipeline connected to the water inlet 34 of the distributor.

[0039] When detergent is put in, after the fixed container 31 detects that the set capacity is reached, the three-way switching valve 7 closes the lower catheter 52, the upper catheter 51 and the flushing pipeline 8 are connected, and the water inlet valve 1 of the washing machine enters Water flushes the detergent in the upper ...

Abstract

The invention discloses an automatic detergent feeding device for a washing machine. The device comprises a washing machine water inflow valve, a detergent container, a distribution device box and a water inflow pipeline, wherein the water inflow pipeline is communicated with the washing machine water inflow valve and the distribution device box; the detergent container is arranged at the bottom of the washing machine and is communicated with the distribution device box through a liquid guiding pipe; the detergent container is used for pressing external air into the detergent container through an air pump, so that internal pressure of the detergent container is increased, and a detergent is lifted into the distribution device box along the liquid guiding pipe; a three-directional changeover value is arranged on the liquid guiding pipe and is used for dividing the liquid guiding pipe into an upper liquid guiding pipe and a lower liquid guiding pipe; a washing pipeline is arranged between the washing machine water inflow valve and the three-directional changeover valve; and the three-directional changeover valve is used for controlling the connection and the disconnection among the upper liquid guiding pipe, the lower liquid guiding pipe and the washing pipeline. The device can be used for accurately adding the detergent; the air pump is used for pressing the external air into the container, so that the air pressure in the container is increased, and the detergent is lifted into the distribution device box along the liquid guiding pipe; and the device has a simple structure.

Description

technical field [0001] The invention relates to a detergent adding device, in particular to a detergent automatic feeding device for a washing machine. Background technique [0002] The detergent used in the washing process of the existing washing machine is placed separately from the washing machine. There is no detergent adding device on the washing machine, and the detergent cannot be added automatically. This structure cannot realize the automatic washing control process of the washing machine. With the improvement of washing machine automation, most washing machines are set to connect the detergent box for placing detergent or / and softener with the water inlet pipeline, and flush the detergent or / and softener in the detergent box into the washing tub through the water inlet However, this structure must first put detergent or / and softener into the detergent box every time the laundry is done, and the automatic laundry control process has not been realized equally.
